Adopted children and their genetic parents and genetic grandparents may not marry. If they do, the marriage will be automatically void (see under heading Marriages which are not valid ) even if they do not know they are related. Adopted children may not marry their adoptive parents but they are allowed to marry the rest of their adoptive family, including their adoptive brother or sister.
People who are step relations or in-laws may marry only in certain circumstances.
